The benefits of adding CBD to your skincare routine
A New Study Shows That CBD Could Shield Skin from UV-A Damage. A recent pilot study, published in the Journal of the American Academy of Dermatology (reported by CosmeticsDesign.com), tested a cream made with CBD or Nano CBD. Participants who applied the cream before UV-A exposure saw impressive results:
Helped prevent the skin from becoming thick and rough after UV-A exposure
Reduced early signs of DNA damage in skin cells
Protected essential parts of the skin’s energy-producing cells (mitochondria) from harm
These findings suggest that CBD may do more than hydrate or calm the skin—it could help defend your skin on a deeper, cellular level. It’s another exciting clue that CBD may become a key ingredient in tomorrow’s innovative skincare solutions.
Understanding UV-A Rays and Their Effect on Skin.
When we think of sun damage, we often worry about sunburn from UV-B rays. But UV-A rays are the silent skin agers. They penetrate deeper into the skin, contributing to premature aging, wrinkles, and even certain types of skin cancer. UV-A rays don’t cause immediate burns, but over time, they trigger oxidative stress and cellular damage that adds up silently.
Backed by Experts, Linked to Korean Research Dr. Adam Friedman, co-author of the study and Professor of Dermatology at George Washington University, pointed out that CBD doesn't just act like sunscreen; it interacts with skin cells to prevent and repair damage.
Interestingly, this builds on findings from a South Korean study by researchers at the Catholic University of Korea, which showed that cannabinoids like CBD could benefit common skin issues like acne, psoriasis, eczema, and even early signs of skin cancer. Together, these studies underscore the growing scientific evidence supporting the use of CBD in skincare.
Why Add CBD to Your Skincare Routine? Your skin is the largest organ of your body—and it does more than hold everything together. It protects you from external threats, helps regulate temperature, and is a key part of your immune defense.
Adding CBD to your skincare routine can help support the skin’s natural functions. It’s been shown to reduce inflammation, calm redness, support healing, and balance. Whether you're managing skin trauma, inflammation, sun exposure, dryness, or breakouts, CBD may help the skin maintain homeostasis (balance) and look its best.
Regular use of CBD-infused skincare products can:
Reduce redness and irritation
Improve skin hydration and elasticity
Soothe stressed or sensitive skin
Support barrier function against pollution and UV damage
